Ka ARM Zenith Radar (KAZR): filtered spectral data, general mode, co-polarized mode - kazrspeccmaskgecopol
收藏资源简介:
The Ka-band ARM Zenith Radar (KAZR) remotely probes the extent and composition of clouds at millimeter wavelengths. The KAZR is a zenith-pointing Doppler radar that operates at a frequency of approximately 35 GHz. The main purpose of this radar is to determine the first three Doppler moments (reflectivity, vertical velocity, and spectral width) at a range resolution of approximately 30 meters from near-ground to nearly 20 km in altitude. \n \nThe KAZR replaces the millimeter-wavelength cloud radar (MMCR) and uses a new digital receiver that provides higher spatial and temporal resolution than the MMCR. In addition, spectral artifacts in the data are significantly reduced in the KAZR, allowing researchers to study cloud dynamics much more closely than with the MMCR.
Ka波段ARM天顶雷达(Ka-band ARM Zenith Radar,KAZR)以毫米波频段开展遥感探测,用以获取云的分布范围与组成特征。该雷达为天顶指向型多普勒雷达,工作频率约为35吉赫。其主要用途是在约30米的距离分辨率下,获取从近地面至近20千米高度范围内的前三项多普勒矩量参数:反射率、垂直速度与谱宽。 KAZR替代了原毫米波云雷达(millimeter-wavelength cloud radar,MMCR),并采用新型数字接收机,相较MMCR拥有更高的空间与时间分辨率。此外,KAZR可显著抑制数据中的频谱伪影,使研究人员能够比使用MMCR时更细致地开展云动力学研究。
